To @ZZ whom it :fn/ay oon/cern..-

Be it known that l, JACOB V. MOTTER, a citizen of the United States,residing at Brooklyn, in the count-y of-Kings and State of New York,have invented certain new and uscfnl Improvements in Driving Mechanism,of which the following is afnll, clear, and exact description, referencebeing had to the aocoinpanying drawings, forming a part of thisspecidcation.

My invention relates more particularly to driving mechanism for cars,such as inspection cars, though it is capable of other uses, and it hasfor its object the improved and si inplified construction of the saine.

The knovelty of my invention Will he hereinafter set 'forth andspecifically pointed out in the claims.

In the accompanying drawings: Figure l is a central sectionin sideelevation of a car ein bodying my invention. Fig. 2 is a plan View indetail of the driving gearing.

The same letters of reference are used to indicate identical parts inboth rigores.

A represents the usual or any suitable car truck with wheels B and axlesO. Snitably supported on the truck at one end is a gasoline engine orother suitable motor D Whose pitinan, as indicated in dotted lines, isconnected to acranic on a shaft E inclined to and suitably jcnrnaled onthe bed of the truck.

F is a fly Wheel upon the rear end of the shaft E whose forward endcarries one meinber c of a universal joint Whose opposing member h is acup-shaped extension of a sleeve G carrying at its rear a circularfriction disk inserted through the sleeve G and having its hearingtherein is the rear end of a shaft, F, substantially in line with theshaft E, and having its eniarged end e conned in the recess of thecup-shaped extension h. Fast upon the shaft F beside the disk H is adog; carrier I in this instance a disk having pivcted in its peripherytwo or more gripping dogs .l adapted toe engage the periphery of thedisk ll to lock the two shafts E, F together. The dogs J have convergentprojections to be engaged hy a Wedging huh l free to slide and carriedupon the shaft F While a hand lever CZ pivoted upon the truck platformand having' a fori; engaging a circumferential groove in the hub K isemployed to shift the hul) to engage and release the dogs from thefriction disk, as will he readily understood. Set screws 7L in theconvergent ends of the dogs are used tc take np Wear and regulate thegrip. The forward end of the shaft F is jonrnaled through a sleeve Lhaving' an upwardly extendinginteriorly' threaded socket f into which isscrewed the lower threaded end of a hand lever O pivoted as at i to thetruck platform. Fast upon the forward end of the shaft F is a beveledpinion M occupying a position between two other beveled gears N fastupon the adjacent car axle in such manner that the shaft F and pinion Mcan be shifted by means of the lever O to engage either of the gears Nat the Will of the operator. By screwingr the lever O into the socket fthe sleeve L can be vertically adjusted to take up weer andto regnlatethe position ofthe pinion il.

P is a seat for the operator located between the levers c?, and O sothat he has ready control of both levers. Of course it is understoodthat by shifting the lever d the shaft F is locked to or unlocked fromthe constantly revolving shaft E to start and stop the car while byshifting the lever O the direction of propulsion is reversed. To holdthe pinion M locked in mesh with either of the gears I have shown a setscrew g engaging a segmentally slotted bracket arm on the car platform,but any other form of lock for the lever might be employed.

Having thus fully described my invention, I claim:

l. A sectional driving shaft, a universal joint for uniting the sectionsthereof, and an interposed clutch for operatively connecting anddisconnecting the sections at Will.

2. A sectional driving shaft, a universal joint for uniting the sectionsthereof, and a clutch comprising' a friction disk carried by one of themembers of the universal joint and clutch arms carried by one of theshaft sections.

3. A sectional driving shaft, a universal joint for uniting the sectionsthereof, a clutch pinion M of the sleeve L, and the operating comprisinga friction disk Carried by one of lever adjustabiy connected withsaidsieeve, the members of the universal joint and tersubstantiaily asdescribed.

minating in a sleeve in which one of the shaft JACOB V. MOTTER. 5sections is inserted, and clutch arms carried NVitnesses:
